Nepal government must think to establish control quality and capacity, ban of old expire aircrafts as well as requires maintenance. This function of body must act like giving air transpiration permits, grounding, eliminating and persecuting to private air transpiration companies. Otherwise, Nepal was facing air accident disasters in past, present and future, too. In Nepal, couple rich people invest money and take bank loans to open air Transportation Company. This company bought cheap old expire Russian aircraft and helicopter which is considerably "Junk". They fix little bit and these companies use these junk aircrafts in Nepal. I would suggest that Nepali government must seriously control junk aircraft from overseas or must setup standard for quality control. Law and regulation must establish for this purpose. Therefore we had lots of air accidents, valuable people dies like this. This is not only.... Almost every 4 months Nepal faces air accidents.
